To all whom it may concern:

Be it known that I, WILLIAM Home, of Floyd, of the county of Floyd andState of Iowa, have invented a new and Improved Spring-Hinge, of whichthe following is a specification The accompanying drawing represents afront elevation ot' my improved spring-hinge for gates, doorsand otherobjects.

The improvement consists in attaching astandard to one leaf of a hinge, and connecting a springencircledextension thereof with the pintle of the hinge, as hereinafter morefully described.

In the drawing, A represents the hinge, of suitable size and material,and attached in the usual manner. A standard, B, is firmly riveted orotherwise connected to that part of the hinge which is applied to thestationary frame or post of the door, being bent up so as to form apin-extension, a, of the hinge A. A spiral spring, C, is coiled aroundpin-extension c, and attached with its upper end to a perforation, b, ofthe swinging part of hinge A, and with its lower end to a similarperforation, b', of standard B. i

Standard B may also be further suitablyk Vconnected by screws orotherwise to the door duces the shutting of the latter, securing also atthe same time sufficient resistance against the accidental blowing up bythe wind or otherwise.

The standard and spring attachment of the hinge is of compa-ct shape, atthe same time durable and ei'ective, and not liable to get out of order.

Having thus described myinvention, I claim as new and desire to secureby Letters Patent- The standard B, attached to one leaf of the hinge,and provided with the pintle-extension c, encircled by the spring G,connected at its ends with both hinge and standard, all as shown anddescribed.
